Algal oil is an oil from marine algae that is rich in certain omega-3 fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
Certain algae species are grown in agriculture specifically to produce algal oil. It can be made from a variety of species, including Crypthecodinium, Nannochloropsis, Schizochytrium, Prototheca, and Ulkenia. The fatty acids in the oil might reduce swelling and help with brain function.
People use algal oil for preventing preterm birth. It is also used for improving thinking skills, physical performance, autism, ADHD, depression, and many other purposes, but there is no good scientific evidence to support these uses.
Don't confuse algal oil with specific types of algae, such as blue-green algae, brown algae, chlorella, or laminaria. Also, don't confuse algal oil with DHA or EPA from other sources such as fish oil, krill oil, or cod liver oil. These are not the same.
